Block (periodic table)

A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are:

The block names (s, p, d, f and g) are derived from the spectroscopic notation for the associated atomic orbitals: sharp, principal, diffuse and fundamental, and then g which follows f in the alphabet.

The following is the order for filling the "subshell" orbitals, according to the Aufbau principle, which also gives the linear order of the "blocks" (as atomic number increases) in the periodic table:

The "periodic" nature of the filling of orbitals, as well as emergence of the s, p, d and f "blocks" is more obvious, if this order of filling is given in matrix form, with increasing principal quantum numbers starting the new rows ("periods") in the matrix. Then, each subshell (composed of the first two quantum numbers) is repeated as many times as required for each pair of electrons it may contain. The result is a compressed periodic table, with each entry representing two successive elements:

Development history

Before The Elder Scrolls

Prior to working on The Elder Scrolls series, Bethesda had worked predominantly with sports and action games. In the six years from its founding to Arena's 1994 release, Bethesda had released ten games, six of them sports games, with such titles as Hockey League Simulator, NCAA Basketball: Road to the Final Four ('91/'92 Edition), and Wayne Gretzky Hockey, and the remaining four adaptations from other media, primarily the Terminator series. Bethesda's
course changed abruptly when it began its first action role-playing venture. Designer Ted Peterson recalls: "I remember talking to the guys at Sir-Tech who were doing Wizardry VII: Crusaders of the Dark Savant at the time, and them literally laughing at us for thinking we could do it." Ted Peterson worked alongside Vijay Lakshman as one of the initial designers of what was then simply Arena, a "medieval-style gladiator game."

Block (rural Australia)

Block is an Australian term for a small agricultural landholding. Block settlement has been used by Governments to encourage decentralization and during financial depressions to give families of unemployed workers an opportunity (frequently illusory) to become primary producers. It may also refer to a lifestyle choice or "hobby farm" for those with an independent source of income.

In parts of Australia, parcels of land of around 6 to 20 acres (2 to 8ha) were allocated by Government to working-class men at nominal rent during the depression of the 1890s with the object of giving them work and, potentially, a source of income. Some eventually prospered, but those on marginal land were doomed to failure. Proponents of the "block system" included George Witherage Cotton. Holders of such allotments were referred to as "blockers" or "blockies".
